tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt (Operator)


tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt — Test if the internal representation of a tuple is of type integer.

Herror tuple_is_int(const Hlong T, Hlong* IsInt)

Herror T_tuple_is_int(const Htuple T, Htuple* IsInt)

HTuple HTuple.TupleIsInt()


tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt tests if the internal representation of the input tuple TTTTTt is of type integer. In that case the value 1 (true) is returned in IsIntIsIntIsIntIsIntIsIntisInt, otherwise the value 0 (false) is returned. If a tuple consists of integer elements only, IsIntIsIntIsIntIsIntIsIntisInt can nevertheless be 0 in case the internal representation is H_TYPE_MIXED; see tuple_typetuple_typeTupleTypetuple_typeTupleTypeTupleType for details.

Exception: Empty input tuple

If the input tuple is empty, the operator returns 1.

HDevelop In-line Operation

HDevelop provides an in-line operation for tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt, which can be used in an expression in the following syntax:

IsInt := is_int(T)


Even if all tuple elements are of type integer, tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt returns 0 (false) if the internal representation of the tuple is of type H_TYPE_MIXED. To test if the elements of the tuple are of type integer the operator tuple_is_int_elemtuple_is_int_elemTupleIsIntElemtuple_is_int_elemTupleIsIntElemTupleIsIntElem should be used.

Is the input tuple of type integer?

Example (HDevelop)

tuple_is_int ([3.1416,'pi',3], IsIntA)
* IsIntA = false
tuple_is_int ([1,2,3], IsIntB)
* IsIntB = true  
tuple_is_int ([], IsIntC)
* IsIntC = true


If the parameters are valid, the operator tuple_is_inttuple_is_intTupleIsInttuple_is_intTupleIsIntTupleIsInt returns the value 2 (H_MSG_TRUE).
